These bugs made these quests impossible to complete.
1-3. These bugs have already been reported on the master thread http://royals.ms/forum/threads/revised-quest-bugs-list.15140/ 4. Empty potion bottles do drop, at a very low rate (took me ~1-2hr personally to complete this quest by non-stop hitting boxes, iirc). http://royals.ms/forum/threads/increase-hitable-obejct-drop-rate.12485/
To me, you achieved the impossible for finding those empty bottles. Thanks for the answer. If admin could just delete this solved thread, that would be nice.
